Plasma-assisted zif-8 modified carbon fibers and methods of making and using the same
By using a plasma-assisted ZIF-8 modification method, oxygen-containing functional groups were introduced onto the surface of carbon fibers and ZIF-8 nanocrystalline layers were grown in situ. This solved the problem of weak bonding between carbon fibers and resin/ceramic matrices, and achieved simultaneous improvement in interfacial bonding strength and mechanical properties.

AI Technical Summary
Existing technologies struggle to achieve efficient interfacial bonding between carbon fibers and resin/ceramic matrices without compromising the strength of the carbon fiber itself, and single modification methods are insufficient to simultaneously improve interfacial bonding strength and mechanical properties.
A plasma-assisted ZIF-8 modification method was adopted, in which oxygen-containing functional groups were introduced into the carbon fiber surface through oxygen plasma activation treatment, and ZIF-8 nanocrystalline layers were grown in situ on the carbon fiber to form a multi-level synergistic modification interface structure, thereby enhancing the interfacial bonding strength and mechanical interlocking effect.
It significantly improves the surface roughness and activity of carbon fiber, enhances the interfacial bonding strength, improves the overall mechanical properties of composite materials, and maintains the bulk strength of carbon fiber.
